I looked around behind the rear seat for a plug for the hardtop, but was unable to find anything that looked like a dummy plug. But then again, I also don't know what I am looking for, or even where to look for it.
I rammed my arm under the pleather covers inside the convert mechanism and felt around, but didn't find any "loose" wires. I also forced the rear seat apart in a few locations, but nothing became evident. Any other advice for me to check, I'll do it!
Thanks all.
